Is EPDM modified bitumen?

There are a number of flat roofing systems available, some of which include EPDM (Ethylene Propylene Diene Monomer), and Modbit (Modified Bitumen). While each has its advantages and disadvantages, these are two of the more common systems used in residential and commercial applications today.

Are EPDM and bitumen compatible?

The Problem with EPDM However, this is problematic due to the fact that EPDM is not compatible with bitumen, or petroleum-based, products. Asphalt shingles are practically solid sheets of petroleum.

How long does bitumen roofing last?

12-20 years
While Built-up roofs have the shortest roofing system lifespan of any material in the study, modified bitumen is right behind lasting 12-20 years on average, just slightly better than the poorest performer.

What is modified bituminous membrane roofing?

Modified bitumen is thought of as the evolutionary cousin of the built-up roofing systems (BUR) that have been used on low-slope roofs for more than 100 years. It is made of asphalt combined with polymerized rubber or plastic, then reinforced with fiberglass to create a rugged-yet-flexible waterproof membrane.

Is polyethylene compatible with asphalt?

Low-Density Polyethylene (LDPE) is the most commonly used PE polymer for asphalt modification [11,12,13,14].

What is EPDM coating?

EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas.

What is EPDM made from?

EPDM is a copolymer with elastomeric properties, which means it is a polymer which is both viscous and elastic. If stretched, it will return to its original shape. Its two main components (ethylene and propylene) are both derived from oil and natural gas.

How can you tell if a roof is bitumen?

Try looking at the material edges: modified bitumen roofing is thicker, and its edges are sealed by heating with a torch – you should see a little runout of melted bitumen at the material seams.

Is modified bitumen a good roof?

Modified Bitumen Roofing Systems are designed to withstand harsh exposure to extreme environmental elements. With five layers of protection, it’s one of the most trusted flat roofing systems used in the industry today.

Is TPO compatible with asphalt?

*Note: EPDM, flexible (plasticized) polyvinyl chloride—PVC, uncured neoprene and TPO are not compatible with rubberized asphalt.

What are polymer modified asphalt?

Polymer modified bitumen (PMB) is bitumen (asphalt) combined with one or more polymer materials. This modification is done with the aim of enhancing the mechanical properties of the bitumen material.
